Dynamic IP
Client Lease Time
•
The Client Lease Time is the amount
of time a network user will be allowed connection to
the Router with their current dynamic IP address. Enter
the amount of time, in minutes, that the user will be
“leased” this dynamic IP address. The range is 5-43,200
minutes. The default is
1440
minutes.
Dynamic IP Range Start/End
•
Enter a starting IP
address and ending IP address to create a range of
available IP addresses. The default range is
100-149
.
(Make sure the Router’s LAN IP address is not in this
dynamic IP range.) For example, if the Router uses the
default LAN IP address,
192.168.1.1
, then the starting
value must be 192.168.1.2 or greater.

DNS
DNS Server 1-2

WINS
WINS Server
Windows Internet Naming Service (WINS)
is a service that resolves NetBIOS names to IP addresses.
WINS is assigned if the computer (DHCP client) requests
one. If you do not know the IP address of the WINS server,
keep the default,
0.0.0.0
.
